Millions of users to benefit from Windows 11's new performance boost on Adobe Photoshop

Microsoft and Adobe are boosting Windows performance of Photoshop by up to 20% using SPGO optimizations.

Despite the advent of AI-generated imagery, Adobe's Photoshop remains one of the most popular tools on this planet. Adobe does not have a publicly reported total user count but it's probably not wrong to assume there are millions. As of 2025, Adobe Creative Cloud has had approximately 41 million paid subscribers, many of whom likely use Photoshop. In addition, more than 166,000 companies worldwide are apparently also using the app. These figures are according to a very recent report by SQ Magazine.

Out of them, it is fair to assume that many are probably running Windows. As such, there is good news for these users as Microsoft has announced Photoshop is getting a big 20% performance boost on x86-64 (AMD64) systems and a 13% bump-up on Arm devices.

This is definitely great news for them as many have complained about the slow performance and general sluggishness of Photoshop on Windows 11 ever since the advent of the latter back in 2021.

If you are wondering how Microsoft managed to do this, the answer lies in a combination of compiler-level optimizations and a technology called Sample Profile Guided Optimization (SPGO). According to Microsoft, Adobe worked closely with the company’s Visual C++ team and adopted the latest MSVC toolchain enhancements together with SPGO to squeeze more performance out of Photoshop’s CPU-bound workloads.

Unlike traditional Profile Guided Optimization (PGO), which requires developers to create special instrumented builds and run lengthy training workloads, SPGO gathers performance data directly from optimized release binaries. This means Adobe could collect real-world usage information which gives a major advantage to this technique, as companies could leverage data collected from actual customer workloads rather than only relying on synthetic benchmark runs. In theory, this should allow optimizations to better reflect how users interact with software in the real world.

Thanks to this, there are improvements to code layout, function inlining, hot-and-cold code separation, and other low-level tweaks that help processors execute instructions more efficiently. Essentially the compiler is better able to identify “hot” code paths, those which are most frequently executed, and optimize them accordingly.
